SSD Write Endurance 25nm Vs 34nm

[Ao1]

Well, I didn't expect any really huge differences between the intel 520 and other sandforce drives.

What will be interesting to see is:
a) Where MWI=1 happens, which I should be able to predict soon.
b) If the device dies like other sandforce drives tested here do, at about 2x of MWI in a horrible flaming insta-death, or if it manages to hang on like the m4 does.

Haven't seen a 60gig sandforce drive hit 700TiB like we have with the m4, would be nice to see if it were possible!

If you look at the at the 320 product manual it explains how SMART metrics can be used to calculate the amount of wear incurred over a duration of time. (I assume it is the same for the 520).

To establish this you need to reset the timers, which can be done with smartmon, or more conveniently with HDSentinel. As ASU is more or less a consistent workload it should be possible to reset the timers, establish the wear percentage factor and then accurately project the amount of writes to get to MWI 0.

Anand did an article about it here:

Intel also covered it in a podcast but I can't put my finger on it just now.
